Firefox: Enable/Disable Referrer

You can enable or disable the referrer from being reported to web sites that you visit with this Firefox tweak.

1. Type about:config in the address bar and press Enter.

2. Find the entry that says Network.http.sendRefererHeader and double-click on it.

3. Set the entry to one of the following:

  • 0 – Disable referrer.
  • 1 – Send the Referer header when clicking on a link, and set document.referrer for the following page.
  • 2 – Send the Referer header when clicking on a link or loading an image.

    “One question: Are there disadvantages to having be at “0″ – meaning “Send No Referrer”? Will it have consequences elsewhere, such as access to certain things?”

    Yes. If a website uses the referer to redirect from a logoff page, for example, you will not be able to leverage that feature.
    Webmaster often assume a regular user will never change that.
    You should never mess with the referer or several applications may stop working for you without notice.

    This is great to know. And it seems it is a significant matter of security, and tracking user activity too.

    Thanks, I was looking for this along time ago, I found an addons that do the same thing, but I didn’t like it so much.

    Thank You so much for all your help.

    I was just recently having problems with trying to log in to my Instagram and for some reason, when I tried the login attempt, it said there was an error and my web browser referrer head was disabled. I followed these exact steps, and it worked!

    In FF 9.0.1 the name is:
    “network.http.sendRefererHeader”
    I got to it by just typing “sendref” in the filter

    Network.http.sendRefererHeader I can’t find it. I used the filter, scanned manually, and tried ctrl+f nothing.
